RE9 will still be a long ways off. It will come out after whatever Itsuno started working on comes out.So if I've got it right, Capcom were originally working on RE8, Village and Revelations 3.
RE8 was taking a while in development and Village was shaping up really well, so it got 'upgraded' to being RE8.
Do we know what happened to the original RE8 project? Has it just become RE9 now? Makes me wonder if we won't have to wait too long between 8 and 9 if it's been in development for so long.
